Development carried out which led to the second generation of ISAL(R) techn
ology is presented. A balance of its most relevant features and benefits fo
r reducing gasoline sulfur content, and octane control is given. Also, a cu
stomer evaluation concerning impact of recently approved specification on g
asoline sulfur content is included. It is stressed out that application of
ISAL(R) technology satisfies the need of refiner to meet this specification
with minimal octane loss, and slight disruptions of its refinery operation
s.
